To all 107mm it may concern:

Be it known that I, Louis. 'WnnsnL, citizen of the United States,residing in los Angeles, in the county of Los Angeles and State ofCalifornia, have inventednew and useful Improvements in Door and WindowBolts, ottwhich the following is a detailed specification.

This invention relates to bolts for fastenin g doors, window sashes,gates and the like,

and especially to means for placing a trio tional drag on sliding boltbars to frictionally retain them in the positon 1n 'WlllCl] they werelast manually set. In addition. I

' have provided means whereby, after the'bolt bars have been shotcompletely home, increased resistance is offered to -initial unlockingmovement, thus rendering it dillicult for intended intruders to work'thebolt back by inserted tools between the bolted door and its jainb.

I obtain the requisite'friotional drag on the bolt bar by the insertionof a spring between the bar and the bolt plate, and, in this way, Ieliminate the-necessity and PX- pense of accurately fitting the bolt barto its keepers, ,the spring taking up all'play between them. i

in the manner in which I have utilized the spring as a detent forpurposes of limiting the extent of bar withdrawal movement, I accomplishthis by notching the underside of the bolt bar, the end of the springbeing adapted to engage the shoulder formed by the notch when the boltis withdrawn to full unlocked position-and thus prevent furtherwithdrawal of the bar to retain the plate and bar in assembled relation.

By reason of the novel construction employed, the assembling of the boltis. verv vkeepers to pro ide for a snug fit therebeeasily accomplishedwithout the aid of tools. The spring is provided with a projection whichis adapted to protrude into a positioning socket formed in the baseplate. In

.sernbling, the bolt bar is merely thrust movement between the bar andthe bolt plate.

Other features of novelty and objects of the invention will be pointedout in the following detailed description, reference being had to theaccompanying drawings, in

which lug. 1 1s a longitudinal medial section taken through a boltwhichembodies my invention 1 Fig. 2 is a View similar to Fig. 1 butshowing the bolt thrust into full locked position;

Fig. 8 is atop-planview of the bolt with the bolt bar removed to exposethe spring member of my device; and

Fig. 4- is a perspective view of the pie terred form ofspring member.

In the drawings, numeral. 10 indicates the base member or bolt plateupon which the bolt bar 11 is mounted and adapted to longitudinallyslide. Keepers or guides 12 and 13 guide bar 11 in its longitudinalmovement,

and, in the present instance, plates 10 and keepers 12, 13 are integral.This, however, is not alimitation on the invention as the keepers may beof any of the well known r types. Handle 1i provides means for man- Aspecial feature of the invention resides the bar in set position and tooffer a certain amount of resistance to the movement of-the bar duringits reciprocation. It is evident that spring 14 obviates the necessityolf accurately forming or machining the bar and tween. I t

In the particular embodiment illustrated, I have shown a novel means'for anchoring or positioning spring 15 on plate 10. The central portion16 of the spring is depressed to form shoulders 17, while plate 10 ispunchedout to form a socket 18 to receive portion 16. The engagement ofshoulder 17 and the side edges of portion 16 with the walls of aperture18 serve to prevent. other than limited lateral and longitudinal rela= tve movement between the plate and the spring. While the constructionillustrated screws, but the illustrated inetho'd'is superior 19 in thatno special anchoring operation is necessary to properly position thespring with respect to the base plate and thei'bar, the springmerelyFbeing' placed on the plate =vritlr portion 16 inregistrywithaperture 18 '15 and barll thrust throughkeeper 13, over "thespring,andthrough keeper 12, whereupon the springnis definitely]')()Sli'.l0il(l. But a single punchingand forming. opera- .tion onplate1.0 is necessarytoform keepers iZO 12*and13 and to provide aperture1S'and screw holes19, after-which single-punching operation theentireplate is readyfor sembly.

To limit the movement of bar 11.to the right as-vieWedin Fig. 1an'd=to-'thus prevent mintended Withdrawal of the bar from its keepers,I mutilate or .notchthe 'underface of bar 11 at 20 to vprovicle shoulder20 spring being adapted to thrust the bar into frictionalengagement-with the keepers, and

S'houlder 20 -is'so located'on'bar 11 that I when the bar is completelywithdrawn "from 'locking position (as inFig; 1) the end 21 r of spring15 engages a the shoulder 220 and th'us prevents fur'ther Withdrawal of'the bolt. Thus spring15 acts as adetentfor *Should occasion arisefor'disas sembling the'bolt, a thin instrument maybe inserted betweenthebar and the rapper 'face of spring '15 and the spring forced down-=-wardly 1 and out of' notch-20, whereupon the bar may be completelywithdrawn from its keepers.

Whenbar11 is shot'homeinto socket K,

a secondary notch 22 on'the under face of bar 11 is entered'by-spring'end -21. "The face 22 formed by notch 22-is engaged-by springend-21 to offer increased resistance to initial bar Withdrawal movementtto arevent the i bolt becoming unintentionally unl ockedfrom i ano1vibrationandto render itdifficult to work the 'bar back and out ofsocket ICby inserting tools between the door and its jamb from 1 theoutside ofthe bolted door.
